ABSTRACT:
A plurality of portions of an open-end spinning machine are dynamically coupled to a plurality of magnetic discs for generating a plurality of pulse sequences indicative of the operating speed of the spinning unit portions, i.e., sliver supply speed, yarn withdrawal speed, etc. The so-generated sequences of pulses are routed through a cyclically operated multi-tap switch into a main and an auxiliary binary counter. The output states of the various counters are out-pulsed to a memory and to a data transmission line after being filled during each switching interval of the multi-tap switch, such interval normally being set by a clock pulse generator. In order to generate ratios of the measured quantities, i.e., the machine draft, the clock pulse generator is overridden and the auxiliary counter initially measures a quantity (i.e., the sliver input rate) indicative of the divisor of the ratio. The auxiliary counter output state representative of such divisor is temporarily stored and outpulsed to the enabling input of the auxiliary counter during the time that the multi-tap switch outpulses, to the main input of such counter, a pulse sequence indicative of the dividend of the ratio (i.e., the yarn withdrawal rate). The resulting count on the auxiliary counter is, like the count of the main counter, outpulsed to the memory and/or the data transmission line.
